Definitions

  • Unit dose detergent product with a transparent solid part Unit dose detergent product with a transparent solid part.
  • the invention is directed to a unit dose machine dish wash detergent product comprising cues for glass-cleaning functionality.
  • Automated machine dish washing generally involves several phases, such as a wetting phase, a phase wherein the soil is released from the wares, a rinsing phase and often a drying phase.
  • Unit dose detergent products placed inside an enclosed detergent holder cup may release different actives at different phases.
  • the actives in a unit dose detergent product may have different functionality, such as bleaching, soil release and avoiding soil redeposition.
  • the manner in which the unit dose detergent product actives provide cleaning benefits during the automated washing process is normally not visible to the consumer. The consumer faces the problem of having to gauge the cleaning benefits afforded by a unit dose machine dish wash detergent product by the sensory cues provided by the unit dose as such.
  • different layers, colour or physical phases e.g. liquid, powder, solid
  • a particular challenge is providing a functional unit dose detergent product which can cue that the product has a particular benefit for cleaning glassware, whilst at the same time is function and also maintains/restores transparency and shine to the glassware.
  • a unit dose detergent product comprising at least one transparent solid part, wherein the transparent solid part comprises detergent active, and wherein the at least one transparent part has a total Light transmittance of at least 30 %, based on a path-length of 10 mm; and wherein the at least one transparent part has a degree of Light scattering of less than 50 %.
  • the invention provides a unit dose detergent product comprising at least one solid functional, transparent part, and wherein the at least one transparent part has a total Light transmittance of at least 30 %, based on a path-length of 10 mm; and wherein the at least one transparent part has a degree of Light scattering of less than 50 %.
  • the invention provides a unit dose detergent product comprising an unbounded solid functional, transparent part, and wherein the at least one transparent part has a total Light transmittance of at least 30 %, based on a path- length of 10 mm; and wherein the at least one transparent part has a degree of Light scattering of less than 50 %.
  • the invention provides a unit dose detergent product comprising an unbounded transparent part.
  • unit dose machine dish wash detergents do not exist on the market.
  • unit dose machine dish wash detergents exist which contain transparent liquid/gel parts these do not communicate glass-cleaning benefits as effectively largely because they must, due to their state, be enclosed in film.
  • PVA films do not cue glass cleaning performance effectively.
  • PVA films are merely seen by the consumer as convenient wrapping or packaging and not associated with cleaning benefits provided per se during machine dish wash.
  • the applicants have found that tuning transparency of at least a solid part of the unit dose detergent composition, which contains detergent active is able to cue this effectively. It is believed due to the fact that such a solid transparent part is able to better resemble the characteristics of clean, clear glass and can provide optimal visual cues to the consumer for glass cleaning benefits.
  • “functional” as used herein means performing a cleaning function and preferably a glass cleaning function.
  • the functionality may be detergency as herein described.
  • Light means light having a wavelength from 330 - 700 nm.
  • Transparent means that the total Light transmissivity through the at least one transparent solid part is at least 5%.
  • the solid part has a total Light transmittance of at least 40%, 50%, 60%, 70%, 80 %, still even more preferably from 83 to 99% and most preferably from 83 to 90 %.
  • the transparent solid part is capable of parallel Light transmittance, meaning the transmitting of Light without appreciable Light scattering.
  • the degree of Light scattering is less than 40%, 30%, 20%, 10%, 5%, 3%, 1 %.“Scattering” as used herein preferably refers to both wide angle scattering and small angle scattering. Wide angle scattering causes what is referred to as haze or loss of contrast, whereas small/narrow angle scattering reduces the see-through quality or clarity. Hence it is preferable that haze is minimized and clarity maximized by minimal narrow and wide angle scattering.
  • the Light transmittance provides the measure of the transparency of the transparent solid part.
  • the solid should at the same time preferably have low wide and small angle scattering to reduce haze and maximize clarity.
  • the total Light transmittance, wide angle scattering and small angle scattering are measured using a Haze-Gard I - Transparency Meter (SHBG4775), and according to the following method:
  • the total Light transmittance, wide angle scattering and small angle scattering are measured according to Supplier instructions and are based on a path length of 10 mm.
  • the solid part has:
  • Glassy means that glassy part comprises minimal scattering centres such as fluctuations in density (e.g. crystals) or composition, but generally this can be visually determined. Besides having high total Light transmittance, and low wide and small angle scattering, it is beneficial that the transparent solid part is also glassy. Gloss is the fraction of light that is reflected in a specular (mirror-like) direction. The angle of the incident light at which gloss is measured is 20 degrees to obtain a measurement for‘high gloss finish’, 60 degrees for‘mid gloss finish’ and 85 degrees for ‘matt finish’. Good gloss attributes better cue glass cleaning performance of the transparent solid. These gloss values are measured using a Rhopoint IQ
  • the solid transparent material has the following gloss properties to provide even better glass-cleaning cues:
  • a specular reflectance at 20 degrees of incident light of at least 5%, 10%, 15%,
  • the reflectance at 20 degrees of at most 95%, 90%, 85%, 80% and more preferably at most 75%.
  • the most advantageous reflectance at 20 degrees being from 40 to 85%, more preferably from 50 to 80 % and even more preferably from 55 to 75%.
  • a specular reflectance at 60 degrees of incident light of at least 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40 %, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%,
  • the most advantageous reflectance at 60 degrees being from 50 to 99.5%, more preferably from 70 to 99.0% and even more preferably from 80 to 98.5%.
  • a specular reflectance at 85 degrees of incident light of at least 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40 %, 45%, 50%, 55% and even more preferably at least 60%.
  • the reflectance at 85 degrees of at most 95%, 90%, 85%, 80% and more preferably at most 75%.
  • the most advantageous reflectance at 85 degrees being from 40 to 85%, more preferably from 50 to 80 % and even more preferably from 55 to 75%.
  • the transparent solid part has the preferred reflectance at 20, 60 and 85 degrees in combination (i.e. has a good high gloss finish and a good mid gloss finish and a good matt finish).
  • solid as used herein is according to its commonplace usage.
  • a wineglass is considered a solid in common place usage although in a strict physical sense it is an extremely viscous liquid.
  • a key feature is that the solid is unbounded: it does not need a firm boundary to substantially retain its structure/shape. So unlike liquid or gel unit dose products which are generally enclosed in water soluble film, the transparent part of the invention does not require this. Outer packaging around the unit dose product may be used but this is not required to exert shaping forces on the transparent part, but may simply be used to convey brand messages.
  • the solid part is present in at least one coherent volume of from 0.1 to 20 cm 3 , more preferably from 0.2 to 15 cm 3 , even more preferably from 0.4 to 10 cm 3 , most preferably from 0.5 to 5 cm 3 .
  • Said preferred volumes allows the transparent solid part of the invention to be easily visible to the naked eye, allowing it to be better appreciated for its visual appeal.
  • One aspect of a solid is that it may not require enclosing - in contrast to a liquid which would require some sort of enclosure such as water-soluble film.
  • the transparent solid part has a smooth surface, preferably a specular surface.
  • Tactile experience plays a further important role in communicating to the consumer that the transparent solid has glass cleaning benefits. Also in this respect it is important that the tactile experience should be glass-like in experience and be sufficiently hard to the touch. Therefore, it is beneficial that the transparent solid part is not be easily deformable by hand, when considered at 20 degrees Celsius. As such it is not a soft gel.
  • the unit dose detergent product according to the invention comprises at least one transparent solid part.
  • unit dose has a certain weight and comprises the transparent solid in a certain weight %.
  • the preferred weight of the unit dose is from 1 to 50 grams, 2 to 40 grams, 5 to 30 grams and even more preferably from 10 to 25 grams.
